If it's ';pure'; olive oil, not extra-virgin. If it's very green in color, or it smells strongly of olives, you don't want to use it; it will make the brownies taste like olives. If it's yellow and has no odor, go for it. If you can't use your olive oil, you can use corn oil, canola oil, or melted butter. (If you need to use melted butter, increase the amount by about 10%, and decrease the amount of water or milk by the same amount, since butter has some water in it.)
Noooooooooo, they'll taste AWFUL!
